Effects of Thickness and Defect Material on Perovskite Solar Cell Efficiency

This work aims to investigate the effects of two parameters on a solar cell with perovskite as the absorption material. As the natural energy resources are available in abundant quantity on earth, the cost of utilizing these resources is less compared to the cost of fossil fuels like petrol, diesel, and similar non-renewable energy sources. There is a need to identify, utilize and enhance the performance of renewable energy sources. Renewable energy is a source of pure, limitless, and increasingly abundant energy. They vary from fossil fuels in their diversity, quantity, and their use anywhere on the earth. They do not emit greenhouse gases and do not cause pollution. Solar energy is obtained from the sun's radiation. These Radiations are converted to electricity, and this electricity is used for home and industrial purposes. This research examines the performance of a perovskite-based solar cell by varying the thickness and defect density of the material. The efficiency of the cell is calculated based on the variation of Defect density and thickness. The thicknesses of the layers varied, and accordingly, efficiency was calculated. Efficiency is reduced to 24.84% when defective material is added to the current construction. When the absorber layer's thickness is changed from 0.03 to 0.09 μm, efficiency rises to 34.24%. The recorder shows the waveforms between the efficiency and the thickness of different layers. The simulation of a perovskite solar cell is done using the SCAPS 1D simulation tool.
